Experience

  • Represent private equity-owned Wayne Fueling Systems, formerly a division of General Electric, which manufactures fuel dispensers for petroleum retailers and commercial fleets, and compressed natural gas fueling pumps. Mintz handles worldwide patent and trademark strategy and prosecution, and enforces those protections in the US and abroad. The firm's relationship attorney serves as outside patent counsel and sits on the patent review committee, working directly with the company's stakeholders in developing patent strategy.
  • Advised medical device client on developing and implementing a post-litigation strategy. Having lost a patent litigation (in which they were represented by another law firm), Mintz attorneys helped the company assess whether they could keep their product on the market during the appeal process. We then provided advice on how to create possible design-arounds for the product to ensure it was clear of infringing the patents at issue, in the event that the appeal was unsuccessful.
  • Developed an IP strategy for a start-up company that designed a cap for user in monitoring compliance for inhalers to treat asthma. Built a successful portfolio based on the strategy, which led to a successful exit.

Citrix decision in 2015. To help answer some of those pleas, the U.S. Patent and Trademark Office (USPTO) published a Federal Register notice on January 7, 2019 to address issues under 35 USC § 112.

Understanding Antedating of a Prior Art Reference for a Patent

April 17, 2019 | Blog | By Christina Sperry

The Federal Circuit’s decision in ATI Technologies ULC v. Iancu (April 11, 2019) highlights the proper standard to use in evaluating whether a claimed invention was reduced to practice before the effective date of a prior art reference.

The general rule is that a patent claim’s preamble does not limit the claim unless the preamble gives life, meaning, and vitality to the claim.  The Federal Circuit’s recent decision in Arctic Cat Inc. v. GEP Power Products, Inc. (March 26, 2019) considers the situation where a patentee wants a preamble to be a required claim limitation, unlike the more typical situation where a patentee does not want a claim preamble to be limiting, such as in Pacing Technologies v. Garmin International previously discussed HERE.  The court deciding in Arctic Cat that the preambles at issue were not required claim limitations highlights important considerations for patent application drafting and for crafting post-issuance arguments.

February 6, 2019 | Blog | By Christina Sperry, Elissa Kingsland

On January 23, 2019, the Federal Circuit decided Supernus Pharmaceuticals, Inc. vs. Iancu and shed light on Patent Term Adjustment (PTA).  PTA was established by the American Inventors Protection Act of 1999 and codified at 35 U.S.C. § 154(b), which defines three kinds of United States Patent and Trademark Office (USPTO) delays, “A” delay, “B” delay, and “C” delay, and sets forth certain reductions from the summation of the Type A, B, and C delays.  One of these reductions relates to Applicant delays.  For an overview of PTA, see our prior articles here and here.

As in any technology area, it is important to consider patent protection early in the development of an AI-related invention. However, AI inventions raise a number of particular issues that, if not addressed fully or at the right time, could be fatal to securing U.S. patent protection that would otherwise be available to prevent others from making, using, selling, or importing the invention. This article identifies common pitfalls in getting a patent for AI inventions and provides insights on how to avoid them. These principles apply not only to AI-related inventions, but also to digital health inventions more broadly.
